Placing a piece of a photograph on another photograph?

[BML]

I have taken a photograph of a child's doll which I would like to impose, if that's the correct term, onto the coal tender of a steam engine I also photographed. Could someone please suggest a simple editing software that I could use.

You want to create a 'photo composite', you would use something like Photoshop (paid) or Gimp (free).

What Dan said really. GIMP is quite capable of producing good results.
